OUNDATION Fieldbus/PROFIBUS (Option)
The optional MT100 F
OUNDATION Fieldbus/PROFIBUS interface is provided by the J26 Phoenix connector terminals. The connector
accepts 26-14 AWG (0.14 mm
2
-1.5 mm
2
) wire (refer to Table 2, page 23 for wire size vs. length info). Connect the MT100 to a
Fieldbus/PROFIBUS device/network as shown in Figure 26 below. Use the provided cable clamp to secure the wires to the board. Note
that devices are connected in parallel (star fashion). For Fieldbus, a terminator (1 µF capacitor and 100 Ω resistor in series) is used on
farthest ends of the trunk (i.e., at each end of the segment cable). For details on PROFIBUS operation refer to the MT100 PROFIBUS PA
manual 06EN003474. For details on F
OUNDATION Fieldbus operation refer to the MT100 FOUNDATION Fieldbus manual 06EN003472.

IELDBUS/PROFIBUS ADD-ON CARD DIAGNOSTICS/TEST JUMPERS
As shown in Figure 20 on page 23, a bank of 0.100" jumpers control the optional Fieldbus/PROFIBUS add-on card’s #SIM_ENABLE
(JP18), #NV_ERASE (JP19), and #HW_LOCK (JP20) test signals. This provides a means to activate a “simulate mode” for Fieldbus
conformance testing and for add-on card testing/diagnostics. Enable a particular signal by installing a 0.100" jumper shunt over the
appropriate header pins. For normal use none of these jumpers are installed.

Relay Outputs
The MT100 relay interface is provided by the J11 Phoenix connector terminals. The relay connector accepts 28-16 AWG (0.14 mm
2
-1.5
mm
2
) wire. Using J11 connect the SPDT relay outputs to the appropriate external circuits as shown in Table 4 below. Relay Contact
Rating: 6 A (resistive load).
